GEOLOGICAL RELIEF MODELS 



(Section of Rocky Mountains prepared under the direction of Professor Rollin T. Chamberlin. 



The cut above shows the first of a series of models we are prepar- 

 ing under the direction of the Geological Society of America to 

 illustrate sections of the United States and Canada that are par- 

 ticularly interesting from a geological standpoint. 



We are at present working on three more of these models, which 

 should be ready by the first of the year, as follows: Section of 

 Greylock and Hoosac Mountains, to illustrate the geology of the 

 Green Mountains; Section of Southern Appalachian Mountains; 

 Section of the Piedmont Province. 



Let us send you circular 251 describing the Rocky Mountains 

 model.
